The event received mainly enormous negative reviews from users, due to the catalog items being promotional, and the event having almost nothing to do with Christmas. Others have criticized it for the little-to-no effort and sponsor ROBLOX is promoting. Users also criticized the event's games for lazily hiding the prizes, making many of them believe they are very simple to obtain and lacking any sort of challenge.
